COMPOSITION HORSESMOE.

SPECIFICATION forming part of Letters Patent No. 776,772, dated December 6, 1904.

Application filed August 8, 1903. Serial No. 168,836. (No model.)

To all whom, 'llt mfr/1,' con/cern:

Be it known that 1, HARVEY BARTLEY, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Composition Horseshoes, of which the following is a specification, reference being' had therein to the accompanying drawings, forming part of this speciiication, in which- Figure 1 is an under plan view of my improved horseshoe. Fig. 2 is a crosssection taken on the line II H of Fig. 3. Fig. 3 is an upper plan view of the metal base. Fig. Il is a partial sectional View -si1nilar to Fig. 3, showing a modiiied construction.

My invention relates to improvements in composition horseshoes in which a cushioning portion is incorporated with a holding-base, and it refers more particularly to the construction of the base and to the supporting and anchoring devices for the cushioning portion whereby these parts are securely incorporated with each other.

Referring now to the drawings, 2 represents the base, made in one integral piece of metal, preferably of forged or cast steel or aluminium, the sides of which are recessed at 3 and provided with the usual nail-holes 4.. rEhe toc 5 is reinforced, as indicated, and is provided with the usual upwardly-extending tip dof suitable form to engage the toe of the hoof. The inner edge 7 of the base is preferably continued around for the full length of the shoe and of the saine depth as Athe toe 5, being somewhat thickened at the rear portion, as indicated at 8, and adapted as thus formed to Vprovide a surrounding rigid holding-frame for the cushion and also a wearing edge adapted to bearupon the pavement. Extending backwardly from the toe 5 is a web portion '9, terminating in a 'downwardlyturned lip l0, forming an anchor adapted to engage and hold the cushion. Each end of such back-V wardly-extending anchor is preferably recessed or narrowed, as at 11, the terminal corners projecting' so as to approximate a dovetail shape, which will maintain a irrn binding hold upon the cushion. At the inner portions of the heels of the base are provided, similar inwardly-projecting holding anchors or extensions 12, the ends of which are preferably recessed in a similar manner, as at l1, and provided with similar holding-lips 10.

Between the forward and back holding-anchors 9 and 12. arranged along the inner edge of the base, area series of inwardly-extemling tongues or anchors 13, arranged in pairs and deflected toward each other. By this arrangement a wedge-shaped cavity 14 is provided between the adjacent anchors forming each pair, into which the cusl'lioning substance will be forced and in which it will be iirinly held.- The anchors 13 are preferablytapered, and between each pair the oppositely-extending anchors 13 conveniently merge into the base by a concave face 15, formingl a recess or cavity into which the cushioning' substance will also be forced. These supplemental anchors are of the :full depth of the base, as in Fig. 2, or of a less depth, as in Fig 4L. As thus constructed it will be seen that all of the holdinganchors extend generally inwardly and that the recessed cavities between them and around them, both as to the anchors 13 and with the anchors 9 and 12, provide an eiiicient holding means for the cushion. The number of the holding-anchors and their location at the front, back, and intermediate portions of the base provide substantial bearing-surfaces against which the cushion will press and by which it will be well supported.

While the arrangement of the anchors as shown is productive of goed results, it is obvious that it-may be varied, as by eliminating' the front and back dovetail-formed anchors and providing one continuous series of the anchors 13 with the intervening wedge form or other equivalently-formed recesses 14 and concave recesses 15. lt will be understood that by the term wedge form l mean to include any cavity wherein the interior crossarea is greater than its entrance-opening, whereby an enlarged holding-body is secured between the closer adjacent anchors.

The cushioning' substance, which is either of rubber or a combination of rubber and canvas or of any other suitable combinations or other materials, is indicated by the numeral 16 and is pressed into the holding'- cavities and around the anchoring' portions and tongues of the shoe-base, so as to completely fill such cavities and surround the holding' devices, as clearly shown. It Will be understood that the cushioning substance is preferably forced around and over the entire upper portion of the base, thus providing' a g'ood bearing-surface for the hoof.

ln attaching the shoe the nails are driven through the openings le and the upper cushioning layer and into the hoof in the usual manner.

As thus constructed I have provided a very serviceable and eflicient horseshoe capable of long-continued use and of holding' the cushioning substance tightly to the base without displacement under the excessive Wear or jar incident to devices of this kind.

Changes and variations may be made by the skilled mechanic in the design, proportions, or other details of the inventiongas, for instance, the number, location, and shape of the holding-anchors; but all such are to be con sidered as Within the scope of the following claims.

That l claim isl. A horseshoe-base having pairs of inwardly-extending oppositely-inclined tapered holding-anchors providing intervening Wedgeshaped cavities, With alternate concave recessed portions forming the outer Walls of said anchors, substantially as set forth.

2. A horseshoe-base provided at its toe and heel portions respectively With inwardly-extending' holdinganchors of dovetail form and intervening series of pairs of inwardly-extending oppositely-inclined tapered holdinganchors providing' intervening Wedge-shaped cavities, substantially as set forth.

3. A composition horseshoe consisting of a base provided at its toe and heel portions respectively With inwardly-extending' holdinganchors of dovetail form, and intervening pairs of inwardly-extending oppositely-inclined holding-anchors providing' intervening Wedge-shaped cavities, and a cushioning' substance incorporated therewith, substantially as set forth.

In testimony whereof l aflX my signature in presence of two Witnesses.
